What Guys Said 1

When things got so serious that I found it would just be easier if she stayed in my house and cooked and cleaned rather than just continually coming over :P

No but seriously, if a girl is spending loads of time at my house like days, I'd probably just ask her to get her sh*t and bring it over. But its not like it was in the past 50 years where its almost as ceremonious as an engagement. It'll sort of just happen.. I hope this helps.
